Dear student
Please find the solution to the asked query:

The electrolyte given is MaNb
So dissociation of the electrolyte gives:
Given that Vant Hoff factor =iDegree of dissociation=αThus MaNb↔aMb+ + bNa-1-α         αa          αbThusTotal amount of species = 1+(a+b-1)αVant Hoff factor i = 1+(a+b-1)α1           α   =i-1(a+b-1)
